Product life cycle getting short, production schedule getting tight, and customer demands getting diverse. Facing such challenging environment, the manufacturing enterprises have to improve the agility or responseness of their manufacturing system significantly for their survival in the market. Manufacturing agility or responseness is exactly what “Agile Manufacturing” is aiming to reach. However, to reach the ideal of Agile manufacturing is totally by no mean to be a trivial task. A manufacturing execution control system (MECS), which is robust, configurable, easy to construct and fit to real practice in industry is required. Here in this research, we only focus on the manufacturing execution control of a manufacturing cell rather than the whole manufacturing plant. Nevertheless, the concept of holonic architecture was adopted to model the whole manufacturing system, including manufacturing cell and its subsidiaries. Also, multi-agent system architecture was employed to design a manufacturing cell execution control system which intend to be robust, reconfigurable, easy to construct and fit to the real practice in industry. The designed system is expected to be able to effectively and flexibly integrate the whole system horizontally and vertically so as to facilitate the ideal of agile manufacturing. In this research, the whole operation in the manufacturing cell execution control was divided into two layers: managerial decision layer and operational control layer. The operation in the managerial decision layer was modeled by event-driven process chain (EPC), while the operation in the operational control layer was modeled by MED-CPN, which is Modularized Event Driven Color Petri-Net proposed in this research. Based on EPC and MED-CPN, an agile manufacturing cell execution control system was designed for a generic agile manufacturing cell (GAMC), which was also proposed in this research for capable of modeling almost any kind of agile manufacturing cell.
